I made a few PSK31 QSO's today sending in DATA-A mode.
However, I like the apparent benefit to PSK-D mode where there is no need to
watch ALC levels.
I use FSK-D for RTTY which works very well with no need to watch audio levels.
In PSK-D, I can Key and send PSK. In the monitor I hear what

Your last comment about using DX4WIN makes me think you're trying to use
software to send PSK while in D mode. D mode is strictly for using a key
paddle and the K3's internal decoder. You were probably just sending a
constant idle signal and pounding away on the computer's keyboard.

But is does, Frank. My K3 will transmit merrily between 7.2 and 7.3MHz,

I have a TRF 40 MHz noise receiver about 500 KHz wide that generates
blanking pulses. The idea was stolen from the Collins which had an
accessory blanking receiver for the KWM2. In my case it blanked by
momentarily interrupting the LO to the first mixer of the receiver,
providing essentially
Hi All,
I've had many QSO's with Don, W6JL, on 40 CW. He hangs out there nearly
every morning. His station is ALL homebrew, a fact he will beat you to
death with everytime you talk to him. In fact, much of his station lays
across his desk in sections, rather than neatly packaged in a case.
Note that the writer, in calling for better noise blankers, says he doesn't
need noise blankers! Still, they are useful at certain times and the
Elecraft blankers do a very good job for me, making high-impulse repetitive
noise virtually disappear. Examples of such noises are the buzz from cheap
The problem with a second receiver tuned (significantly, like Collins) out of
band is that the noise isn't always the same at the two frequencies.
IMHO, the problem with most blankers, as mentioned below, is that the designers
don't introduce any delay in the signal path. It takes some time to

Hey gang:
When installing the KPA100 in an EC2 enclosure, should I install the

Not sure if hooking up the KPA100 / KAT100 in the EC2 will mute the

Just curious

Jerry,
The speaker in the KPA100 will not be active when mounted in the EC2
enclosure unless special provisions are made for connecting it.
Never-the-less, I recommend mounting and wiring it in case you ever
decide to mount it on the base K2 (or sell the KPA100).
